| tyre pressure
I have been reading your posts on tyre pressure with some interest. I race full size motorcycles as well as a bizeta powered polini rep. When talking to the 125 gp guys at the recent hartwell motorcycle championships i recieved the most valuable piece of advice.
Bassically the advice was as follows: "run tyres as soft as you can get away with." to determine this:
1. messure the tyre pressure when the tyre is cold
2. use tyre until the tyre is at full operating temperature (2-3 laps)
3. messure tyre pressure while tyre is hot
4. If the gain in tyre pressure is greater than 2 pounds the tyre pressure was too low. If the tyre is unable to gain 1 pound the tyre pressure is too high.
For a zongya slick, with me (65 kg) riding, optimum starting pressure was 14.5-16 psi, far lower than i expected. When i tried this, the bike was stable and cornered hard all the way to the edge of the tyre. It was such a success that i now use the method on my full size race bike, now running 13psi it has never handled better!
This results because more traction achieved is when the traction patch is of a greater area.
